Judge to Decide Next Step in HD Patent Suit
An attempt by 14 radio broadcast groups to unite efforts to
fend off a patent infringement lawsuit targeting their HD Radio data and voice
transmissions is facing a new challenge. Wyncomm and an affiliated company,
Delaware Radio Technologies LLC, in court filings have asked a federal judge to
deny a request by broadcasters to consolidate 14 separate lawsuits so the case
HD Radio developer iBiquity Digital Corp. filed suit in July
against Wyncomm and DRT claiming the patents in question are invalid. Broadcasters
then requested iBiquity, as the developer and seller of HD Radio technology, go
first with its suit to determine the validity of three patents at the center of
Judge Gregory Sleet will decide whether the broadcasters can
consolidate their cases and then be granted a stay while the iBiquity suit
Wyncomm says in its most recent court filing, “Defendants
provide no cognizable reason why the cases against the defendants should not
proceed,” and asked the judge to deny the broadcasters’ request.
The broadcasters named as defendants are Beasley Broadcast
Group, CBS Radio, Clear Channel parent CC Media Holdings, Cox Media Group,
Cumulus Media, Entercom, Entravision, Greater Media, Hubbard Radio, Radio
Disney, Radio One, Saga, Townsquare Media and Univision.
The two plaintiffs first filed suit against the radio
broadcasting companies in November 2013, alleging the broadcasters are
infringing on three patents it owns, including patent # 5,506,866 entitled
“Side-Channel Communications in Simultaneous Voice and Data Transmission.” All
three patents have since expired.
Previous attempts by Radio World to contact Wyncomm and DRT
for comment have been unsuccessful.
